A 1.00 g sample of limestone is allowed to react with 100 cm^3 of 0.200 mol/dm^3 HCl. The excess acid required 24.8 cm^3 of 0.100 mol/dm^3 NaOH solution. Calculate the percentage of calcium carbonate in the limestone

Two identical flowering plants are planted in neighboring yards. one plant grows tall and healthy, producing numerous pink flowers. the other is small, has brown leaves, and never flowers. what could be the difference between the

1. Identify the sentence the contains a verb phrase. A) African Violets are an excellent choice for an indoor garden. B) These plants are relatively easy to grow. C) They require very little natural light. D) You can grow them

Carbon is also removed from the atmosphere during the process of weathering. carbon dioxide combines with water to form carbonic acid. this reacts with calcium silicate (in rocks) to produce calcium ions, bicarbonate ions and

Frost wedging is a form of weathering caused by water seeping into the cracks of rocks. This type of weathering is common in regions that have very cold winters. How does frost wedging take place? A) This is a physical weathering

I need an equation for the neutralization of lemon juice (citric acid) with baking soda (sodium hydrogen or sodium bicarbonate) that shows a proton transfer to form carbonic acid and a salt..And an equation for the decomposition

A student did an experiment with two identical plants, Plant 1 and Plant 2. About 10 mL fertilizer was added to Plant 1. About 200 mL of water was added to each plant every day. The height of the plants was recorded over a period

When surface water dissolves carbon dioxide, carbonic acid (H2CO3) is formed. When the water moves underground through limestone formations, the limestone dissolves and caves are sometimes produced. CaCO3(s) + H2CO3(aq)
